<p>Together with <a class="link" href="GtkSocket.html" title="GtkSocket"><span class="type">GtkSocket</span></a>, <a class="link" href="GtkPlug.html" title="GtkPlug"><span class="type">GtkPlug</span></a> provides the ability to embed
widgets from one process into another process in a fashion that is
transparent to the user. One process creates a <a class="link" href="GtkSocket.html" title="GtkSocket"><span class="type">GtkSocket</span></a> widget
and passes the ID of that widget’s window to the other process,
which then creates a <a class="link" href="GtkPlug.html" title="GtkPlug"><span class="type">GtkPlug</span></a> with that window ID. Any widgets
contained in the <a class="link" href="GtkPlug.html" title="GtkPlug"><span class="type">GtkPlug</span></a> then will appear inside the first
application’s window.</p>
<p>The communication between a <a class="link" href="GtkSocket.html" title="GtkSocket"><span class="type">GtkSocket</span></a> and a <a class="link" href="GtkPlug.html" title="GtkPlug"><span class="type">GtkPlug</span></a> follows the
<a class="ulink" href="http://www.freedesktop.org/Standards/xembed-spec" target="_top">XEmbed Protocol</a>.
This protocol has also been implemented in other toolkits, e.g. Qt,
allowing the same level of integration when embedding a Qt widget
in GTK+ or vice versa.</p>
<p>The <a class="link" href="GtkPlug.html" title="GtkPlug"><span class="type">GtkPlug</span></a> and <a class="link" href="GtkSocket.html" title="GtkSocket"><span class="type">GtkSocket</span></a> widgets are only available when GTK+
is compiled for the X11 platform and <code class="literal">GDK_WINDOWING_X11</code> is defined.
They can only be used on a <span class="type">GdkX11Display</span>. To use <a class="link" href="GtkPlug.html" title="GtkPlug"><span class="type">GtkPlug</span></a> and
<a class="link" href="GtkSocket.html" title="GtkSocket"><span class="type">GtkSocket</span></a>, you need to include the <code class="literal">gtk/gtkx.h</code> header.</p>
